It looks legit. I don't know much about it - I'm still a noob - but the pins are right. It looks a little cheap (Like it could split easily) and the diagnostics has all failed but one. Also, I think I managed to update it, I'm not sure, but booting into GW mode is damn near impossible. I press 'A' and million times and it's really finicky. I'm on 9.0 BTW.

If the FPGA update worked, then it's not a fake AFAIK.
Sounds like it might be DOA though.
I would ask them for a replacement.

As for the question in the title, eachmall has been very reliable for me, they're just slow. But they're reliably slow, I know it's going to take a long time but it's cheap and I know it'll be legit

Follow this tutorial down to the T. Minus the bit about new 3ds and tell us if it works correctly http://maxconsole.com/maxconsole_files/v3.1.pdf . In my opinion it seems fake as i've held 4 different gateway cards and they all have a slight bump on the pin side where you would insert your micro sd card.

Even go as far as formatting the SD card used for both your 3ds and micro sd card for the gateway red cardM

Yeah, that's the one I used the second time. I used one on Maxconsole that was pretty much the same, minus the L-Button hitting on the browser exploit. Didn't realize you needed to do that on the browser launch.

1)Format you SD card for the 3DS using this https://www.sdcard.org/downloads/formatter_4/eula_windows/index.html
2)Format your Microsd card using an adapter to the exfat format.
3)put 1 rom any rom onto the micro sd card
4) place Launcher.dat onto your 3ds sd card the latest is 3.2.2
4)start your 3ds go to the browser and type https://go.gateway-3ds.com WITHOUT THE RED CARD IN!
5)click format Emunand and wait for it to finish.
6)restart the 3ds and go to the gateway menu again and click run diagnostic while you have the red card in, if everything passes (the red card should light up with 4 different colors) click launch gateway mode with a
7)while in the 3ds home menu press select to bring up the rom selecter.
